なお、真円形状の貫通孔２１a，３１ａを例示したが、長孔形状であってもよい。延伸部３の延伸方向に間隔をおいて設置した２つの棚９の間側（棚９の間の通路側）に保持部２が張り出すように配置する際の保持部２の位置合わせに都合がよい。
また、棚９の間（複数列並んだの棚９の中央付近）に保持部２（照明装置７）が配されるように、延伸部３の長さを設定（調整）してもよい。
具体的には、棚９の間の中央付近に保持部２（照明装置７）が配されるように適切な長さの延伸部３を使用する。 (2) Stretching section This will be explained mainly using FIG. 2.
The extending portion 3 has a pipe shape. The extending portion 3 here is configured in the shape of a rectangular pipe with a rectangular cross-sectional shape. The extending portion 3 has a cross-sectional shape and dimensions that do not change in the longitudinal direction.
The front end portion 31 of the extending portion 3 is detachably connected to the holding portion connecting portion 21 of the holding portion 2 . The extension part 3 (front end part) is configured to have a size that can be inserted into the holding part connecting part 21 and fits into the inner circumferential surface, and has an outer circumferential shape that substantially matches the inner circumferential shape of the holding part connecting part 21. . This restricts the holding part 2 from rotating with respect to the extending part 3 with the front-rear direction as the rotation axis.
The front end portion 31 of the extension portion 3 has a fixed portion that is fixed to the holding portion connecting portion 21 . A screw is used for fixing, and the fixing portion is constituted by a screw hole or a through hole 31a. Note that the through hole 31a is provided so as to correspond to the through hole 21a of the holding portion connecting portion 21 so as to pass through the two opposing plate portions.

The rear end portion 32 of the extension portion 3 has a through hole 32a similarly to the front end portion 31. The through hole 32 a constitutes a fixing portion to be fixed to the connecting portion extension side connecting portion 41 of the connecting portion 4 .
Note that although the through holes 21a and 31a are illustrated as having a perfect circular shape, they may have a long hole shape. Convenient for positioning the holding part 2 when the holding part 2 is arranged so as to protrude between two shelves 9 installed at intervals in the stretching direction of the extending part 3 (on the path side between the shelves 9). Good.
Further, the length of the extending portion 3 may be set (adjusted) so that the holding portion 2 (lighting device 7) is arranged between the shelves 9 (near the center of the shelves 9 arranged in a plurality of rows).
Specifically, the extension part 3 of an appropriate length is used so that the holding part 2 (illumination device 7) is arranged near the center between the shelves 9.

（３）接続部
主に図２を用いて説明する。
接続部４は、延伸部３の後端部３２と接続する接続部延伸側接続部分４１と、上下方向に延伸する支柱部分４２と、固定部５に接続される接続部固定側接続部分４３と、接続部延伸側接続部分４１と支柱部分４２における上端部と連結する連結部分４４とを有する。 (3) Connection section This will be explained mainly using FIG. 2.
The connecting portion 4 includes a connecting portion extension side connecting portion 41 that connects to the rear end portion 32 of the extending portion 3, a support portion 42 extending in the vertical direction, and a connecting portion fixed side connecting portion 43 that connects to the fixed portion 5. , the connecting portion has an extension-side connecting portion 41 and a connecting portion 44 that connects to the upper end of the support portion 42 .

接続部延伸側接続部分４１は、延伸部３の後端部３２と嵌合することで、後端部３２と接続する。ここでは、接続部延伸側接続部分４１は、後端部３２内に挿入される（内嵌）。接続部延伸側接続部分４１は、横断面形状が「コ」字状をし、ここでは、上側が開放している。「コ」字を構成する３つの板部分は、延伸部３の後端部３２の３つの板部と接触（対向）するように構成されている。これにより、延伸部３と接続した状態で、延伸部３のガタツキを抑制できる。また、これにより、接続部４に対して、延伸部３が前後方向を回転軸として回転するのが規制される。
接続部延伸側接続部分４１は、延伸部３に固定される固定部分を有する。固定には、例えばねじが利用され、固定部分がねじ孔又は貫通孔４１ａにより構成される。貫通孔４１ａは、前後方向に間隔をおいて複数個（２個）ある。なお、貫通孔４１ａは、延伸部３の貫通孔３２ａに対応して、対向する２つの板部分を挿通するように設けられている。なお、貫通孔３２ａが設けられている２つの板部分は、「コ」字を構成する開放（上部）している部分に隣接する板部分である。
なお、貫通孔３２a，４１aは長孔形状であってもよい。保持部２を棚９の間側に保持部２が張り出すように配置する際の保持部２の位置合わせに都合がよい。
加えて、上述した貫通孔２１aと貫通孔３１a、貫通孔３２aと貫通孔４１aをそれぞれ長孔形状にしてもよい。保持部２を棚９の間側（棚の間の通路側）に配置する際の位置合わせに更に都合がよい。 The connecting portion extension side connecting portion 41 is connected to the rear end portion 32 of the extending portion 3 by fitting with the rear end portion 32 . Here, the connecting portion extension side connecting portion 41 is inserted into the rear end portion 32 (internal fit). The connecting portion extension side connecting portion 41 has a U-shaped cross section, and is open at the upper side. The three plate portions forming the “U” shape are configured to contact (oppose) the three plate portions of the rear end portion 32 of the extension portion 3. Thereby, wobbling of the extending portion 3 can be suppressed in a state where it is connected to the extending portion 3. Furthermore, this restricts the extension portion 3 from rotating with respect to the connection portion 4 with the front-rear direction as the rotation axis.
The connecting portion extension side connecting portion 41 has a fixed portion fixed to the extending portion 3 . For example, a screw is used for fixing, and the fixing portion is constituted by a screw hole or a through hole 41a. There are a plurality of (two) through holes 41a at intervals in the front-rear direction. Note that the through-hole 41a is provided so as to correspond to the through-hole 32a of the extension portion 3 so as to pass through the two opposing plate portions. Note that the two plate portions provided with the through holes 32a are plate portions adjacent to the open (upper) portion forming the “U” shape.
Note that the through holes 32a and 41a may have a long hole shape. This is convenient for positioning the holding part 2 when the holding part 2 is arranged so that the holding part 2 protrudes between the shelves 9.
In addition, the through holes 21a and 31a, and the through holes 32a and 41a described above may each have a long hole shape. This is more convenient for positioning when arranging the holding part 2 between the shelves 9 (on the passage side between the shelves).

支柱部分４２は、横断面形状が方形状をし、延伸部３と同様の形状・大きさをしている。これにより、固定具１の意匠性を向上させることができる。支柱部分４２の長さの異なる接続部４を利用することで、照明装置７の設置位置を調整でき、棚板から荷物の出し入れ等の作業や、リフトの通過等の邪魔になるのを防止できる。 The support portion 42 has a rectangular cross-sectional shape, and has the same shape and size as the extension portion 3. Thereby, the design of the fixture 1 can be improved. By using the connecting portions 4 of different lengths of the support portions 42, the installation position of the lighting device 7 can be adjusted, and it can be prevented from interfering with tasks such as loading and unloading luggage from shelf boards, and passage of lifts. .

接続部固定側接続部分４３は、固定部５の固定部接続部分５１と嵌合することで、固定部接続部分５１と接続する。固定部接続部分５１は、延伸部３と同様の構成の角パイプ状をしている。ここでは、接続部固定側接続部分４３は、固定部接続部分５１内に挿入される（内嵌）。接続部固定側接続部分４３は、横断面形状が「コ」字状をし、ここでは、後側が開放している。「コ」字を構成する３つの板部分は、固定部接続部分５１の３つの板部と接触（対向）するように構成されている。これにより、固定部５と接続した状態で、接続部４のガタツキを抑制できる。また、これにより、固定部５に対して、接続部４が上下方向を回転軸として回転するのが規制される。
接続部固定側接続部分４３は、固定部５に固定される固定部分を有する。固定には、例えばねじが利用され、固定部分がねじ孔又は貫通孔４３ａにより構成される。貫通孔４３ａは、上下方向に間隔をおいて複数個（２個）ある。なお、貫通孔４３ａは、固定部５の貫通孔５１ａに対応して、対向する２つの板部分を挿通するように設けられている。なお、貫通孔４３ａが設けられている２つの板部分は、「コ」字を構成する開放（後部）している部分に隣接する板部分である。
なお、接続部延伸側接続部分４１は後端部３２の内側に挿入され、接続部固定側接続部分４３は固定部接続部分５１の内側に挿入されるため、接続部延伸側接続部分４１と接続部固定側接続部分４３はインナーパイプとして機能し、保持部２側に掛かる荷重を支えやすくするという効果も奏することが可能である。 The connecting portion fixed side connecting portion 43 is connected to the fixed portion connecting portion 51 by fitting with the fixed portion connecting portion 51 of the fixed portion 5 . The fixed part connecting part 51 has a square pipe shape having the same structure as the extending part 3. Here, the connecting portion fixed side connecting portion 43 is inserted into the fixed portion connecting portion 51 (internal fit). The connecting portion fixed side connecting portion 43 has a “U”-shaped cross section, and here, the rear side is open. The three plate portions forming the “U” shape are configured to contact (oppose) the three plate portions of the fixed portion connecting portion 51. Thereby, wobbling of the connecting part 4 can be suppressed in a state where it is connected to the fixed part 5. Moreover, this restricts the connection part 4 from rotating with respect to the fixed part 5 with the vertical direction as the rotation axis.
The connecting portion fixed side connecting portion 43 has a fixed portion that is fixed to the fixed portion 5 . For example, a screw is used for fixing, and the fixing portion is formed by a screw hole or a through hole 43a. There are a plurality of (two) through holes 43a spaced apart in the vertical direction.

（４）固定部
主に図４を用いて説明する。
固定部５は、棚９の支柱９１に固定される固定部分５０と、接続部４に着脱可能に接続される固定部接続部分５１とを一体備える。ここでは、固定部分５０と固定部接続部分５１とは溶接により一体化されている。 (4) Fixing part This will be explained mainly using FIG. 4.
The fixing part 5 integrally includes a fixing part 50 fixed to the column 91 of the shelf 9 and a fixing part connecting part 51 detachably connected to the connecting part 4. Here, the fixed portion 50 and the fixed portion connecting portion 51 are integrated by welding.

固定部分５０は長尺状の支柱９１に取り付けられる。このため、固定部分５０は上下方向に長い形状をしている。
固定部分５０は、左右方向から支柱９１と対向する一対の対向板部分５２Ａ，５２Ｂと、一対の対向板部分５２Ａ，５２Ｂにおける前端を連結する連結板部分５３とを有する。連結板部分５３の前面に固定部接続部分５１が設けられている。
対向板部分５２Ａ，５２Ｂは、真円形状又は方形状（ここでは真円形状である）の第１孔５４ａと、第１孔５４ａに対して上下方向（ここでは下方向である）に間隔をおいて設けられ且つ上下方向に長い第１長孔５４ｂとを有している。
なお、対向板部分５２Ａの第１孔５４ａと、対向板部分５２Ｂの第１孔５４ａとは、上下方向に同じ位置にある。換言すると、第１孔５４ａの中心と、第１孔５４ａの中心とを結ぶ仮想線は左右方向と設計上平行である。 The fixed portion 50 is attached to an elongated column 91. Therefore, the fixed portion 50 has a vertically elongated shape.
The fixed portion 50 includes a pair of opposing plate portions 52A and 52B that face the support column 91 from the left and right, and a connecting plate portion 53 that connects the front ends of the pair of opposing plate portions 52A and 52B. A fixed portion connecting portion 51 is provided on the front surface of the connecting plate portion 53.
The opposing plate portions 52A, 52B have a first hole 54a having a perfect circular shape or a rectangular shape (here, a perfect circular shape), and an interval in the vertical direction (downward here) with respect to the first hole 54a. It has a first elongated hole 54b that is provided at a distance and is long in the vertical direction.
Note that the first hole 54a of the opposing plate portion 52A and the first hole 54a of the opposing plate portion 52B are located at the same position in the vertical direction. In other words, the virtual line connecting the center of the first hole 54a and the center of the first hole 54a is parallel to the left-right direction in terms of design.

対向板部分５２Ａ，５２Ｂは、第１孔５４ａに対して前後方向（ここでは後方向である）に間隔をおいて形成された真円形状又は方形状（ここでは真円形状である）の第２孔５５ａと、第２孔５５ａに対して上下方向（ここでは下方向である）に間隔をおいて設けられ且つ上下方向に長い第２長孔５５ｂとを有している。
なお、対向板部分５２Ａの第２孔５５ａと、対向板部分５２Ｂの第２孔５５ａとは、上下方向に同じ位置にある。換言すると、第２孔５５ａの中心と、第２孔５５ａの中心とを結ぶ仮想線は左右方向と設計上平行である。 The opposing plate portions 52A, 52B have a perfect circular shape or a rectangular shape (here, a perfect circular shape) formed at intervals in the front-rear direction (here, the rear direction) with respect to the first hole 54a. It has two holes 55a, and a second elongated hole 55b that is vertically spaced apart from the second hole 55a (downward in this case) and that is long in the vertical direction.

第１孔５４ａは、その中心と連結板部分５３の前面と距離Ｌ１は、例えば、１５[ｍｍ]である。これにより、耐荷重が１５０[Ｋｇｆ]タイプの支柱９１の取付孔に対応できる。
第２孔５５ａは、その中心と第１孔５４ａの中心との距離Ｌ２は、例えば、１５[ｍｍ]である。これにより、耐荷重が２００[Ｋｇｆ]以上タイプの支柱９１の取付孔に対応できる。なお、この場合、連結板部分５３と支柱９１の前面との間に隙が生じすることもある。
一対の対向板部分５５Ａ，５５Ｂとの間の距離Ｌ３は、複数種類に設定されている。例えば、４０[ｍｍ]、５０[ｍｍ]、６０[ｍｍ]に設定されている。これにより、耐荷重タイプの支柱９１の寸法に合わせて、いずれかのタイプを選択することで、殆どの支柱９１に左右方向から対向板部分５５Ａ，５５Ｂが近接又は当接する。これにより、安定した状態で固定部５を支柱９１に固定できる。 The distance L1 between the center of the first hole 54a and the front surface of the connecting plate portion 53 is, for example, 15 [mm]. This makes it possible to accommodate the mounting hole of the support column 91 having a load capacity of 150 [Kgf].
The distance L2 between the center of the second hole 55a and the center of the first hole 54a is, for example, 15 [mm]. This makes it possible to accommodate the mounting hole of the support column 91 having a load capacity of 200 [Kgf] or more. In this case, a gap may occur between the connecting plate portion 53 and the front surface of the support column 91.
The distance L3 between the pair of opposing plate portions 55A and 55B is set to a plurality of types. For example, they are set to 40 [mm], 50 [mm], and 60 [mm]. As a result, by selecting one of the types according to the dimensions of the load-bearing type of support columns 91, the opposing plate portions 55A and 55B approach or abut most of the support columns 91 from the left and right directions. Thereby, the fixing part 5 can be fixed to the support column 91 in a stable state.

１．例１
図６の（ａ）を用いて説明する。
例１の固定具１０１Ａは、保持部２、延伸部３、接続部４及び固定部５を備え、さらに、連結部６Ａを備える。
連結部６Ａは、接続部４の延伸領域４６に設けられ、左右方向に延伸するパイプ状に構成されている。連結部６Ａは、ここでは、横断面形状が方形状の角パイプ状に構成されている。なお、連結部６Ａは、例えば、溶接等により接続部４に固定されている。
連結部６Ａは、延伸領域４６に対して左右方向の両側に延伸している。これにより、左右方向のいずれかに隣接する他の固定具１０１Ａと連結部材６５Ａを介して連結可能となる。
隣接する固定具１０１Ａ同士が連結部材６５Ａを介して連結されることにより、連結されていない場合に比して、棚９に固定された固定具１０１Ａの耐震性の向上に優れ、また、通路上に照明装置７を均一に並べることが可能となる。
連結部６Ａは、対向する２つの板部分を挿通する貫通孔６ａを有している。貫通孔６ａは、延伸領域４６の左右方向の中央を基準にして左右両側にそれぞれある。ここでは、左右両側に複数個（２個）あり、左右方向に間隔をおいて設けられている。貫通孔６ａは、真円状であってもよいし、左右方向に長い形状であってもよい。
これにより、連結部６Ａの貫通孔６ａ、連結部材６５Ａの貫通孔（図示省略）を挿通するねじにより固定できる。
なお、例１の固定具１０１Ａは、接続部４の延伸領域４６に連結部６Ａを備えているが、例えば、図６の（ｂ）に示すように、連結部６Ａを保持部２に備えてもよい。

Here, the connecting portion 6A is configured in the shape of a rectangular pipe with a rectangular cross-sectional shape. Note that the connecting portion 6A is fixed to the connecting portion 4 by, for example, welding or the like.
The connecting portion 6A extends on both sides of the stretching region 46 in the left-right direction. Thereby, it becomes possible to connect with another fixture 101A adjacent to either the left or right direction via the connecting member 65A.
By connecting adjacent fixtures 101A via the connecting member 65A, the seismic resistance of the fixtures 101A fixed to the shelf 9 is improved compared to a case where they are not connected. It becomes possible to arrange the lighting devices 7 uniformly.
The connecting portion 6A has a through hole 6a through which the two opposing plate portions are inserted. The through holes 6a are located on both sides of the stretching region 46 with respect to the center in the left and right direction. Here, there are a plurality of pieces (two pieces) on both the left and right sides, and they are provided at intervals in the left and right direction. The through hole 6a may have a perfect circular shape or may have a shape long in the left-right direction.
Thereby, it can be fixed with a screw inserted through the through hole 6a of the connecting portion 6A and the through hole (not shown) of the connecting member 65A.
Note that the fixture 101A of Example 1 includes the connecting portion 6A in the extension region 46 of the connecting portion 4, but, for example, as shown in FIG. Good too.
In addition, when the through-hole 6a is formed into an elongated hole shape that is elongated in the left-right direction, it is also possible to adjust the fixing position of the screw within the elongated hole depending on the distance from the other adjacent fixture 101A.
